LINOTYPE SQUIRT GUARD Filed 001;. l2, 1956 FI .Z Ff MZy Patented Sept.13, 1938 UNITED; STAT-Es PATENT OFFICE 4 Claims.

The present invention relates to a 'guard for use on Linotype machinesfor preventing the spattering of molten metal during the casting of ablank or typographed slug. Y

As is well knownl in the art after the matrice are set in a line, theline is carried to an elevator for supporting the same and carrying saidline to the casting part ofthemachine. The casting is accomplished thruthe use of a pot containing molten metal, and in the casting operationthe molten metal is squrted thru a restricted opening into the mold. Thesquirting of the metal presents a hazard to the operator of the machinesince it frequently occurs that the metal will spatter, which is causedprimarily when the matrices are loosely held or when they become worn,when the line is improperly justified, when the metal is too hot or toocold, when small fragments of metal adhere to a matrice 2() or spaceband, when space bands slip off the jaws which causes an openingtherebetween, or when a proper lockup is not obtained.

The primary object of the invention therefore is to provide a guardconnected to a Linotype machine and so positioned that the operator ofthe machine will be protected from the spattering molten metal duringthe casting operation.

A further object of the invention is the provision of a guard means foryprotecting the operator from spattering molten metal and at the sametime permit access to the mold and elevator mechanism should theoccasion arise.

The invention will be fully and comprehensively understood from aconsideration of the following detailed description when read inconnection with the accompanying drawing.

Fig. 1 is a side elevation, partly in section, of a Lintoype machine inposition for casting a type slug, the guard being shown in protectiveposi- 40 tion.

Fig. 2 is a front elevational View and illustrating the casting elevatorwith the guard in position; and

Fig. 3 is a perspective view of the guard detached from the machine.

Referring to the drawing for a more detailed description thereof, theLinotype machine herein illustrated consists, briefly, of a pot 5containing molten metal, and having a spout 6 thru which the moltenmetal is ejected into the slot 'l of the mold B. The pot 5 is supportedon the main frame 9 and adapted to pivot thereon thru the arm IE), thepivotal connection not shown.

Intermediate the pot 5 vand the frame 9 is the mold disc II whichsupports the mold 8. The

mold disc ll is mounted on a shaft I2 and is provided with Watercompartments, not shown, for cooling purposes.

The elevator mechanism for holding the matrices during the castingoperation and for transporting to and from the casting operation isindicated generally by the numeral I3, and comprises a longitudinalframe I4 and channeled rails I5. The channeledrails I5 support thematrices I6 and space band I'I as clearly illustrated in Fig. l of thedrawing. The justification mechanism is indicated generally by thenumeral I8. The elements above described comprise a portion of the usualLinotype machine with which the guard is associated.

The guard indicated generally by the numeral I9 is attached to a portionof the machine 20 known as the rst elevator stop, at which point theline of type is transferred to the distributing or second elevator, notshown. 'Ihe guard I9 is attached thru the bracket 2| being secured thrubolts or the like 22, said bracket being pivotally connected at 23 topermit the guard to swing into and out of engagement with the machine.By referring to Fig. 3 0f the drawing it will be noted that the guard isformed of a channel-shaped frame 24 that is substantiallyrectangularshaped. A shatter-proof glass 25 is supported Within theframe on the front, top, and two sides thereof, it being understood thatthe back portion contacting the machine is open as well as the end. Onone side and preferably the side toward the operator there is provided ahinged door 26. For various reasons it may be necessary for the operatorto have access to the casting mold and surrounding parts and it is forthis purpose that the door 26 is provided. It will also be noted thatthe lower end of the door is L-shaped as indicated at 2'I thru whichextends the adjusting mechanism, not shown, for varying the measurementsof the line to be set. The L-shaped portion 2l permits the positioningof the adjusting mechanism and .at the same time allows for the guard tocompletely surround the mold and casting parts to protect the operatorfrom spattering metal. The bracket 2| is also provided with verticalslots 28 thru which the bolts or the like 22 pass for attachment of theguard to the machine, and by means of said slots the guard can beadjusted toward and away from the channel rail l5, being adapted to movea limited distance within said slots.

From the above description it will be apparent that there is provided anew and novel type of guard which protects the operator of a LinotypeCFI CIK

machine from the spattering of molten metal during the casting of ablank or typographed slug. The provision of the guard does not in anymanner interfere with the normal operation of the machine since allparts are visible and readily accessible.

It is to be understood that this improvement is capable of extendedapplication and is not conned to the exact showing of the drawing nor tothe precise construction described and, therefore, such changes andmodifications may be made therein to fit different models of typecastingmachines as do not affect the spirit oil the invention nor exceed thescope thereof as expressed in the appended claims.

What is claimed as new is:

1. The combination with a machine for casting type bars, comprising aholder for type matrices,

a mold cooperating therewith, and means for forcing molten metal into amold, of afnormally relatively stationary shield-pivotally connected tothe machine fory covering the matrices and mold, said shield beingsubstantially rectangular shaped and provided with transparent top, sideand fron-t walls.

`2'. The combinationl with a machine for cast.-

ing type bars, comprising a holder for. type matrices, said holderforming part of an elevator mechanism, arnold cooperating with saidholder, and7 means for lforcing molten metal intoV said mold, of aynormally relatively stationary shield pi-votally connected to the upperend of the machine forcovering the matrices and mold during theY castingoperation, said shield being substantially rectangular shaped andprovided with transparent top, side and front Walls, and means carriedby said shield for permitting access to the casting mold.

3. The combination with a machine for casting type bars, comprising a.holder for type matrices, said holder forming part of an elevatormechanism, a mold cooperating with said holder, and means for forcingmolten metal into said mold, of a normally relatively stationary shieldpivotally connected tothe upper end of the machine for covering thematrices and mold during the casting operation, said shield beingsubstantially rectangular shaped and provided with transparent top,v.side and front Walls, and a door hingedly connected to said shield forpermitting access to the mold and elevator mechanism.
